#1 "Gas whipping around the black hole has no choice but to ride that wave of choppy spacetime sea that distorts everything falling into the black hole," they added.

But enough about your lunch with Mike al-Moor, tell us something about space.

#2 Isn't there a glaring error here? If the stuff in the space-time warp is in a different space-time than us, what exactly are we looking at? What does a time-traveler look like when he's travelling in time? Either a statue or a blur, if that.

#3 It appears there's a nomenclature problem here. For physicists, "space-time" is a single concept. Time still only flows in one direction, and causality is preserved.
In an accelerated frame (orbiting a blackhole, standing on a planet, etc), non-accelerated time seems to pass more quickly. Your time traveller might look like a statue... or more likely a slowly dissipating cloud.

#4 there no sucher thing as time, there is only changing probabilities. trust me on this. kitter cat that jumps after a butterfly, is a different cat when it lands. it's all in the triangles you see

#5 Well if Black Holes distort space-time I guess that gives a rational explanation why the Muddle East is still in the 7th century

#6 To be more precise, gravity distorts spacetime, and black holes are massive gravity sources. Also, they lead to really squishy sandwiches, or is it alternate unverses(universi?).

#7 Didn't there used to be one of these things in Calcutta?

#8 "used to be", which is why Calcutta is no longer stuck in the 7th century.
